[英]how to update xml file from another xml file dynamically?
I would like to update an xml file from another xml file.I have used an xml file as shown below: 我想从另一个xml文件更新一个xml文件。我使用了一个xml文件,如下所示:
one.xml one.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#00BFFF">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:gravity="center" android:visibility="visible">
</LinearLayout>
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:gravity="center" android:visibility="visible">
</LinearLayout>
</LinearLayout>
</ScrollView>
two.xml as follows: two.xml如下:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<int name="linearLayout1" value="8" />
<int name="linearLayout2" value="0" />
</map>
from the above two xml files i would like to change the attribute value one. 从以上两个xml文件中,我想更改属性值一。 xml when if XML,如果
<int name ="linearLayout1" value = "8"/>
from two.xml then I would like to update one.xml file as where LinearLayout android:id="@+id/linearLayout1" then change the attribute value as android:visibility="gone" . 从two.xml然后我要更新one.xml文件,其中LinearLayout android:id =“ @ + id / linearLayout1”然后将属性值更改为android:visibility =“ gone” 。
Here is code what you want it's 这是您想要的代码
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse("/home/riddhish/developerworkspace/SplitString/src/com/updatexmlwithjava/two.xml");
DocumentTraversal traversal = (DocumentTraversal) doc;
Node a = doc.getDocumentElement();
NodeIterator iterator = traversal.createNodeIterator(a, NodeFilter.SHOW_ELEMENT, null, true);
/** * Logic for checking **/ / ** *检查逻辑** /
boolean flag=false;
for (Node n = iterator.nextNode(); n != null; n = iterator.nextNode()) {
Element e = (Element) n;
if ("int".equals(e.getTagName())) {
if(e.getAttribute("name").equals("linearLayout1")){
if(e.getAttribute("value").equals("8"))
flag=true;
}
}
}
/** * Logic for reading one.xml and setting android:visibility="gone" **/ / ** *用于读取one.xml并设置android:visibility =“ gone”的逻辑** /
docFactory = DocumentBuilderFactory.newInstance();
docBuilder = docFactory.newDocumentBuilder();
doc = docBuilder.parse("/home/riddhish/developerworkspace/SplitString/src/com/updatexmlwithjava/one.xml");
traversal = (DocumentTraversal) doc;
a = doc.getDocumentElement();
iterator = traversal.createNodeIterator(a, NodeFilter.SHOW_ELEMENT, null, true);
for (Node n = iterator.nextNode(); n != null; n = iterator.nextNode()) {
Element e = (Element) n;
if ("LinearLayout".equals(e.getTagName())) {
if(e.getAttribute("android:id").equals("@+id/linearLayout1")){
if(flag==true){
System.out.println(""+e.getAttribute("android:visibility"));
e.setAttribute("android:visibility", "gone");
}
}
}
}
/** * Logic for rewriting one.xml **/ / ** *重写one.xml的逻辑** /
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("/home/riddhish/developerworkspace/SplitString/src/com/updatexmlwithjava/one.xml"));
iterator = traversal.createNodeIterator(a, NodeFilter.SHOW_ELEMENT, null, true);
doc = docBuilder.newDocument();
Element rootElement = doc.createElement("ScrollView");
doc.appendChild(rootElement);
for (Node n = iterator.nextNode(); n != null; n = iterator.nextNode()) {
rootElement.appendChild(doc.importNode(n, true));
}
transformer.transform(source, result);
